Ben Howland left Pitt for UCLA. Dixon later did the same for TCU (his alma mater, and after they were out of the league).
Jim O'Brien left BC for Ohio State (though he fell out with the BC administration).
Matt Doherty left Notre Dame, after one year, for UNC.
Providence had a couple of guys go. Rick Barnes for Clemson, and Pete Gillen for Virginia.
Rollie left Villanova for UNLV (what was he thinking?).
I'm sure there are some other that I missed, not counting the ones mentioned earlier, like Holtnann.
